[PATCH, UPDATE] Update audio/csound and audio/csound-manual
Update audio/csound to 5.06
csound has been "liberated" and is now GPL, see
http://csounds.com/VercoeGift.html The corresponding csound
entry in LEGAL should be removed, note that csound-manual
isn't updated to 5.06 and is still subject to a restrictive
license.
With thanks to Erik Trulsson and Mel at -questions for
patch-Top-csound.c
PR: ports/116255

Unbreak port by updating to 4.23.
Triggered by: kris wants to remove broken ports
Approved by: maintainer timeout (he hasn't much time at the moment
and I want to have bugs get reported just in time to
have it fixed before 5.1)
